Class GPane

  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JPanel
                  ch.aplu.util.GPane

All Implemented Interfaces:: java.awt.event.FocusListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.awt.print.Printable, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible

public class GPane
extends javax.swing.JPanel
implements java.awt.event.FocusListener, java.awt.print.Printable
extends javax.swing.JPanel
implements java.awt.event.FocusListener, java.awt.print.Printable

Simple graphics window of similar to GPanel to be used as component in a top-level window (JFrame, JDialog, Browswer window, etc.) using a coordinate system with x-axis from left to right, y-axis from bottom to top (called window coordinates, default range 0..1, 0..1). The drawing methods perform all drawings in an offscreen buffer and automatically repaint it on the screen, so the graphics is shown step-by-step.

A current graph position is used, that remembers the end position of the last drawing process and where new drawings start.

Because its offscreen buffer will be created at the moment when the GPane is displayed, all graphics drawing operations will be blocked until then. You should check with isReady()) before invoking drawing methods. (A GPanelNotReadyException is thrown after a blocking timeout of 30 sec)

GPane is derived from JPanel and can only be used by adding an instance to another top-level window. Unlike GPanel where the constructors and all public methods run in the Event Dispatch Thread, with GPane it is your responsiblity to invoke Swing methods in the EDT.

Constructor Detail

GPane

public GPane()

Create a GPane to be used as embedded graphics component with default size 100x100 pixels. Parameterless bean constructor.

GPane

public GPane(Size size)

Create a GPane to be used as embedded graphics component with given size.

GPane

public GPane(Size size,
             boolean embedded)

Create a GPane with given size. If embedded = true, an embedded graphics component is created; if false, the graphics window has its own frame (like a GPanel).

Method Detail

window

public void window(double xmin,
                   double xmax,
                   double ymin,
                   double ymax)

Set window coordinates. left_x, right_x, bottom_y, top_y

visible

public void visible(boolean isVisible)

Select if GPane's window is visible or not. (You may draw into an invisible GPane and show it afterwards.)

getWindow

public GWindow getWindow()

Return a reference to the GWindow used by the GPane. Can be used to access the surrounding JFrame because GWindow is derived from JFrame.

repaint

public void repaint()

Override JPanel's repaint() to inhibit explicit repainting while printing.

Overrides:: repaint in class java.awt.Component

repaint

public void repaint(int x,
                    int y,
                    int width,
                    int height)

Override JPanel's repaint(int x, int y, int width, int height) to inhibit explicit repainting while printing.

Overrides:: repaint in class java.awt.Component

isReady

public boolean isReady()

Test if GPane is fully initialized. Only used for GPane.EMBEDDED.
(If GPane is embedded in an other component, any graphics drawing operation must be postponed until the parent component is shown because the GPane's size is only known at this time.)
Because yield() is called, it can be used in a narrow loop.

print

public boolean print(GPrintable gp,
                     double scale)

Print the graphics context to an attached printer with the given magnification scale factor. scale = 1 will print on standard A4 format paper. The given gp must implement the GPrintable interface, e.g. the single method void draw(), where all the drawing into the GPane must occur. A standard printer dialog is shown before printing is started.
Return false, if printing is canceled in this dialog, return true, when print data is sent to the printer spooler. (On some platforms the Java Virtual Machine crashes when changing the printer in this dialog. Use the default printer)
Example:



   import ch.aplu.util.*;

   

   public class PrintEx extends GPane implements GPrintable

   {
